Evidence limitation

Automated conformance checks are not complete accessibility evidence

Direct limitation

Automation cannot reproduce every assistive technology, disability interaction, interpretation or user need.

Artifact or claim that may be supported

Static and browser automation can detect many structural, reflow, focus, contrast-adjacent and rendering defects.

What the evidence does not establish

Automation cannot reproduce every assistive technology, disability interaction, interpretation or user need.

Additional evidence required

A PASS can be overstated as universal accessibility.

Mitigation

Publish the test scope and preserve independent manual assistive-technology review as a known limitation.
